RAIL-ANCHOR.

Application filed June 24, 1914.

To all whom it may concern: v w

Be it known that I, Cnamzxon D. PORTER- FIELD, a citizen of the UnitedStates, residing in New York city, in the county of New York and Stateof New York, have invented certain new and useful Improvements inRail-Anchors, of which the following is a specification.

My invention pertains to anchors for pre venting railroad rails fromcreeping. 1

It comprises but two parts, an anchor and a wedge, both blanked fromsteel plates and stamped and bent into their final forms, and thereforeeconomical and adapted to i be turned out in great quantities byautomatic The improvement in my device consists in malnng it from asheet metal stamping,

and is therefore resilient, and so arranging the structure that anycreeping of the rail which it grips, deforms or distorts the device.This distort-ion causes an 1116113386 111 the grip of the anchor uponthe rail, through usual.

s 31, terminating in a Wider butt 32.

the foreshortening of the sides of the triangularlykdisposed base grips,and which foreshortening, together with the above noted resiliency ofthe device, forms the important part of my invention.

Figures 1, 2 and 3 are perspectives. Fig.

1 shows the rail baseand web in section and the mode of putting on theanchor, Fig. 2 shows it in place. Fig. '3 shows one side of the rail andthe anchor head. Fig. 4- is a plan View.

The rail is of common section, with base flanges 2, 2, and is spiked tothe tie, 1, as The anchor 3 is blanked from steel plate and bent intothe shape of a 7. It has a head, 30. broadest at its free edge for alarge abutting face 35, and a narrow tang, Flange notches 33, to fitclosely on the margins of the base are located in the free end of thehead and in the inner side of the butt and a wedge notch. 34, to fit'thebase margin and wedge, is blanked at the junction of the head and tang.The distance from the root of the Wedge-notch 34- to the fluke, 37, ofthe opposite flange-notch, slighl y exceeds the Width of the rail base,so that the anchor can be put on the rail.

The notched anchor plate is bent into shape, the end of the headbent-inward to are'bent outward and the butt flakes 37 bent inward tofacilitate putting the anchor on the rail-base. The wedge 4 is tapered,offset to fit on and ride the raiisfiange and slotted to form a narrowfork -10.

To apply the anchor, the tang 31 is passed nearly at'right angles underthe raii ham with the notches upward and the wedgenotch 34 riding therail-base. The tang 31 is then raised to the base and the butt 32 swungtoward the abutting face 35 to cause the butt-fiukes 37 to ride the baseand the free head fluke 36 to bearing end 35 of the head is raised, andthe Wedge 4 is inserted from within the head, into the wedge notch 34and riding the rail base, which draws the anchor into sliding engagementwith the rail base. The anchor is then driven home, with its face 35against the tie l, the wedge 'l is forced home with a crow-bar which iswedged between the end of said wedge and the inner face of the butt andits fork d0 of the wedge is bent down, to lock the anchor. This mode ofapplication puts the anchor under triangular stress, as indicated by thedotted triangles and the dotted and. full lines of'the head, in Fig. i.

It is obvious that the head 50 resists creeping stresses elastically andtherefore is not likely to gouge the tie as rigidanchors do, and is evenmore reliable in its action; and also that use tightens the grip of theanchor to the base because of the obliquity .cf the tang 31 to the railand the-projection of the head 30 therefrom.

It'is obvious from the foregoing that placed against the tie, and thatthe same clear it; whereupon the tempering the steel,

form a tie face 35; and the head fiukes 36 engage a'railroad rail andtie comprising resilient oppositely arranged rail-base en-' gagingmembers integrally connected, one of said base -,engaging membersagainst the tie, and tension increasing means between said resilientmembers.
